Check for voltage and ground at blower motor connector, hvac turned on, if good voltage and ground with no blower action, suspect the blower motor.

If you missing voltage or ground we can backtrack the circuits.

SOURCE: MY heater fan works on 4 & 5 Only on my 2000 Silverado

remove the passenger side lower insulator panel. behind the panel you wil find the blower motor housing. next to the blower motor housing there will be a wiring connector with 6 to 8 wires going in to it. the connector will be held secure with 2 screws. remove the connector and remove the screws -- this is your resistor. reverse the process to re-install.

My 04 silverado heater control, lost the #1,2,3and 5 fan setting now all are gone, heat and a/c work but fan doesnt turn on, is it just the fan switch on the heater a/c control box?


Usually what happens is the switch goes bad and starts sending multiple current paths to the resistor. Then the resistor pack burns up as well. There is some detailed discussion on this at http://www.fixya.com/cars/t5072781-location_blower_motor_relay

Heater fan not working . changed fuse and nothing Silverado 1500


you can test the motor with a multe tester with ohms capable, locate the heater motor and the wires feeding it there will be 2 find the plug and unplug it, using the tester probe the 2 wires with the red and black from the meter to the motor side, on ohms scale the meter should deflect close to full scale, with a digital it should read around 30 or have at least have a low number but no lower than 20 or so, if you get a reading your motor is probably OK, you can also use the meter in voltage mode and with the heater turned on you should read a voltage higher than 10 on the vehicular side of the plug, if there is no voltage there check to see if you have voltage at the heater fuse, if so than replace your fan control switch,,,good to go

Why does my blower motor for my 97 silverado does not work?


Check for a blown fuse,
Check for faulty blower motor speed control resistor pack - (usually located in the air flow in the blower ducting),
Check the blower motor is ok; ensure it runs if power directly applied to it.
Check blower motor fan control switch is ok.
